SPECIFICATION forming part of Letters Patent No.A 624,820, dated May 9, 1899.

Application filed December f6, 1898. Serial No. 699,418. (No model.)

To @ZZ whom, t may concern.'

Be it known that I, WASHINGTON H. KIL- BOURN, ofGreenield, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Track-Sanding Devices, of which the following is a specification.

This invention has for its object to provide an effective device for supplying sand, salt, rbc., to the rails of railway-tracks and to be operated with the minimum expenditure o t' power.

The invention consists in the improvements which l will now proceed to describe 'and claim.

O f the accompanying drawings, forming a part of this specification, Figure l represents a longitudinal section of a portion of a streetcar provided with a sanding device embodying my invention. Fig. 2 represents a section on line 2 2 of Fig. l, looking toward the left. Fig. 3 represents a section on line 3 3 of Fig. lA Fig. 4; represents a top plan view of the sand-holder shown in the preceding figures. Fig. 5 represents a perspective view showing said holder partly in section. Fig. 6 represents a sectional view of a portion of a car, showing a cam rotated by an axle of the car and connected with a sand-displacing device in the sand-holder mounted on the car. Fig. 7 represents a perspective view of a sandholder embodying a modification of my invention. Fig. 8 represents a section on line S 8 of Fig. 7 looking toward the left. Fig. 9

represents atop view of the construction shown in Fig. 7, together with means for rotating the disk-shaped shovel. Fig. 10 represents a section on line 10 l0, Fig. 9. Fig. 11 represents a section on line l1 ll, Fig. 10. The same letters of reference indicate the same parts in all the iigures.

My improved sanding device comprises a 4 holder'of any suitable constructionfor abody of sand, a substantially horizontal shovel, which isl located below and is in contact with the mass of sand, means for moving said shovel edgewise to cause it to horizontally displacea portion of the sand resting upon it,

` and an outlet arranged to receive the horizontally-displaced sand, the said parts being relatively arranged so that when the 'shovel is moved it will not Vexperience any considerable degree of resistance from the sand above it and will horizontally displace a considerable quantity of sand and supply the same to the Outlet. The shovel may be of any suitable form and construction and may be lnoved `horizontally edgewise by any desired means,

and I here remark that I desireto be understood as. includingin the scope of my present invention, so faras the first claim of this application is concerned, the reciprocating shovelshown in my pending application for Letters Patent of the United States, Serial blo-695,933. I have shown in this application, and have hereinafter claimed more or less specifically, a disk-like shovel connected with the sand-holder by rotative connection, the shovel being adapted to move in a curved path on said connection and to either oscillate or rotate progressively in Vone direction.

I will firstdescribe the construction shown in Figs. l to 5, inclusive, which show the shovel adapted to oscilla-te. In said figures,

o represents the sand-holder, whichis suit' ably secured to the body b of the car, and c represents the shovel, which is a flat plate of disk-like form located horizontally over andy in close proximity to the bottom'of the holder a. The rotative connection between the shovel and the holder is here'shown as including a sleeve` `which is aflixed to the bottornof the sand-holder and projects upwardly therefrom, a socket e, affixed to the shovel c and formed to receive and turn freely upon the sleeve cl, and a shaft f, iixed to the upper end of"the socket e and projecting downwardly through the sleeve d, said shaft being connected -at its lower end with means for imparting a rocking motion to it, f said motion being imparted to the socket e ofV the shovel c, -which is thus caused to oscillate or turnirst in one direction and then in the opposite direction on the bottom of the sandholder. The outlet g of the sand-holder is located at one side of the center of motion of the shoveland the shovel is cut away or re. cessed between the said center of motion and the outlet g, so that the edge of the cut-away portion constitutes virtually the ends of two shovels, one ofvwhich delivers sand when the shovel is turned in one direction, while the other delivers sand when'the shovel is turned in the opposite direction, the result being a nearly continuous movement ofvsand from the holder to the outlet g.

I have shown the sand-holder provided with an inclined guard-plate h, the lower edge of which is separated from the shovel c by a narrow space or throat i, which permits the desired movement of the sand to the outlet by the shovel, but is so narrow that it prevents the accidental escape of ,sand by gravitation when the shovel is not in use. I have also shown the holder provided with an opening j above the outlet g, thebbject of said opening being to permit the escape of damp air that may rise through the ,outlet g and'prevent the same from affecting the body of sand in the holder.

The shaft f may be rocked and the shovel c oscillated by any suitable means. In Fig. l I show as the operating-means a pedal 7c, arranged to be depressed by the foot of the motorman, a bell-crank lever t, arranged to be moved by the pedal, and a rod 7a2, connecting the lever t with an arm 7c3, afiixed to the shaftf. A spring 7a4 is arranged to move the parts in adirection opposite to the motion imparted by the depression of the pedal 7o, so that when the pedal is released the shovel is turned in one direction and when the pedal is depressed the shovel is turned in the opposite direction. The fixed sleeve cl, projecting upwardly from the bottom of the sand-holder, and the socket e, fitted to rotate on said sleeve, enable the shovel to be oscillated readily, the socket e being in contact with the body of sand above the shovel and serving to loosen the sand by its rocking movements therein.

In Fig. 6 I show means for operating a sanddisplacing device in a sand-holder by power derivedfrom an axle of the car.- m represents the axle, and n a cam affixed thereto. 0 represents a lever mounted to oscillate on a fulcrum 1) and having its lower end pressed by an expanding-spring Q against the cam '11,. The upper end of the lever o is connected by a rod r with the sa'nd-displacin g device, which may be a shovel c of the construction above described. When it is not desired to operate the sanding device, the lever o may be made inoperative by means of a slide s, which supports the fulcrum p and is movable in a iixed guide t by means of a lever u, mounted on the car-platform. A spring c normally acts on said slide to hold the lever o in the operative position. (Shown in Fig. 6.) When the lever fu is moved from the position shown, it moves the fulcrum p away from the cam, thus with drawing the lever o from the path of the cam.

In Figs. 7 to ll I show a modification of my invention in which the shovel is given a progressive step-by-step rotation. In said iigures, a represents the sand-holder, and o represen ts the shovel, which in this oase is a complete disk aflixed to a shaft c2, which is journaled in a bearing c3 on the bottom of the sand-holder. To the shaft c2 is affixed a ratchet c4, with which are engaged spring-dogs c5 c6, carried by a bifurcated arm or rod c7, which may be operated similarly to the rod 7a2 (shown in Fig. l) or the rod r. (Shown in Fig. 6.) The sand-outlet g' is located outside the periphery of the disk-shaped shovel. The side of the holder a' adjacent to the outlet g is provided with an opening a2, extending half-wayacross the diameter of the shovel c', the said side of the' holder a having at the opposite side of the center of the shovel an extension as, theloweredge of which isin close proximity to the upper surface of the shovel, so that the shovel, which is rotated in the direction indicated by the arrow in Fig. 7, carries the sand outwardly through the opening a2 and moves it against the extension a3, the latter serving as a scraper, which causes the sand as it accumulates to -iiow outwardly into the outlet g.

It will be seen thatthe shovel in each of the cases above described moves edgewise under the body of sand, and while it supports the weight of the mass of sand in the holder or the greater part of such weight by reason of s its edgewise movement it d'isplaces the sand horizontally and feeds it to the outlet with the minimum of resistance.

While I have called the displacing device c and c a shoveh I do not desire to be understood as limiting myself to a continuous plate ordisk of metal, as a similar result would be produced if the part called a shovel were of open 'construction and were composed, for example, of a series of ilat radiating arms movable edgewise. It is obvious, however, that the continuous-.plate construction is preferable to any open construction, because it moves under the sand with lessresistance, since it presents,when made of disk-like form, no edges to press against and be obstructed by the mass of sand.

It will be seen that by attaching the sanddisplacing shovel to a vertical shaft which extends downwardly through the bottom of the sand-holder the construction of the device is rendered more compact than that shown in my above-mentioned former application, considerably less space being required on and above the "bottom of the car for the sand holder, while the operating mechanism for the displacing device is located wholly below the bottom of the car. The presentimprovement is therefore well adapted for use on open cars, where there is less available space above the bottom ofA the car than in closed cars. The openingt' (shown in Figs. l and 5) and the opening@2 (shown in Figs. '7 and S) may be termed a primary outlet, the tube g, Figs. l and 5, and the tube g', Fig. 7, being a secondary outlet. The function of the said primary outlet in each case is tolimit the' escape of sand from the holder by gravitation and prevent the sand from iowing to the secondary outlet when the shovel is not in operation.

In Fig. l I show the rod k2 provided with a hammer y, arranged so that when the pedal la is released the movement of the rod 7a2 by the spring 7a4 will force the hammer against the outlet g, jarring the latter and dislodging any accumulation of gravel, &c., that may have formed in the outlet.

It will be observed that the sleeve d, projecting above the bottom of the sand-holder c, prevents the escape of sand around the shaft j", while the socket e, covering the sleeve d, prevents the admission of sand to the upper end of the sleeve.
